ANDRZEJ DUPA Virus – Distribution Ways
The ANDRZEJ DUPA virus is a typical malware that is being delivered to target users via the popular means. A typical example is the use of spam email messages that utilize social engineering tactics in order to coerce the users into interacting with the dangerous elements. The virus files may be either hyperlinked or attached directly to the messages. They are are also among the main carriers of virus payloads. Two of the most popular examples are the following:
- Infected Documents — The hackers behind the ANDRZEJ DUPA virus may embed its code into documents of all types: rich text documents, spreadsheets and presentations. When they are opened a message will appear asking them to enable the built-in scripts. If this is done then the threat will be downloaded from a remote location and executed on the local machine.
- Software Installers — The hackers primarily target popular software such as system utilities, creativity suites and even computer games.
Infections with the malware can also be caused through the use of web scripts. This encompasses all manners of banners, pop-ups and redirects. The infections can also affect legitimate sites via affiliate and ad networks.
Another method that is employed by computer hackers is the integration of the ANDRZEJ DUPA virus in browser hijackers. They are malicious browser plugins that are made for the most popular web browsers (Mozilla Firefox, Google Chrome, Safari, Opera, Internet Explorer and Microsoft Edge). Typically they are distributed on the relevant plugin repositories and coerce the users into installing them. Usually the hackers utilize fake credentials, user reviews and elaborate descriptions.
ANDRZEJ DUPA Virus – In-Depth Analysis
The ANDRZEJ DUPA virus is a newly discovered ransomare that is being pushed to users in several attacks. The campaigns themselves are relatively short and frequent which gives us two likely scenarios that govern its operations. The first one is the proposition that the code powering it has been shared on the underground hacker forums and used by different groups. The other hypothesis about the origins of the ANDRZEJ DUPA virus is that its being run by an individual or criminal collective that is rapidly developing the strains.
As it is rapidly expanding different updates to its source code can be made. This means that the different samples may also execute different behavior patterns.
The infections may begin with a data harvesting component that can gather sensitive information about the infected machine and the victim users themselves. The harvested data is categorized into two main types:
- Personal Data — The component is used to reveal sensitive information about the users, specifically their name, address, location, interests, passwords and account credentials.
- Anonymous Metrics — They are used to optimize the campaigns and are composed of strings taken from the operating system and information about the installed hardware components.
The obtained data can be then fed to a stealth protection component. It’s purpose is to scan the running applications for services that can interfere with its execution: anti-virus software, sandbox and debug environments or virtual machine hosts. The malware engine is programmed to bypass their real-time engines or altogether delete the applications. In certain cases the viruses can delete themselves in order to avoid detection.
Follow-up changes can include Windows Registry of different kinds. Usually the engines manipulate already existing strings belonging to user-installed applications and the Windows operating system. As a consequence some functions may stop working and the victims can experience significant performance issues.
Future versions of the ANDRZEJ DUPA virus can also manipulate the boot options which can disallow access to the boot recovery menu. An additional effect can be the institution of a persistent installation that can make the virus execute every time the computer is started.
Advanced Trojan-like behavior is expected to be integrated in future versions. A common way is to launch a specific network component that can connect to a hacker-controlled server. It can be used to spy on the victims in real time and overtake control of the affected machines.
ANDRZEJ DUPA Virus – Encryption Process
The associated ransomware component is launched once all prior processes have completed. It uses a powerful cipher in order to encrypt sensitive user data according to a built-in list of target file types. An example list may include any of the following:
An interesting fact is that it renames the affected data with the same .CRAB extension as the GandCrab ransomware family. In fact the code analysis reveals that it’s no way related to the malware family. The detected samples are using a lockscreen instance in order to scare the users and attempt to manipulate them into paying a ransom decryption fee. The lockscreen is created as an application frame with the ANDRZEJ DUPA title and reads the following message:
HELLO MY FRIEND!!!! I’am very sorry, but all your personal files have been encryptd :(
Shutdown will be erased
What Happened to My Computer?
